To P1ece: What are P1Harmony support advertisements?
Support advertisements are a fan culture where fans purchase advertising space, such as digital signage, outdoor billboards, and ad trucks, at their own expense to display for their bias, timed with birthdays, debut anniversaries, or concert dates. In Korea, they are called "saengil (생일) ads," and they have rapidly spread in Japan since the 2020s.

By putting up support advertisements synchronized with member birthdays and group anniversaries, you can visibly express your love for your bias. Furthermore, by displaying them near venues or in crowded areas like Shibuya and Shinjuku, other fans and the general public will have the opportunity to see them.
